We were meeting friends for lunch yesterday and decided to go early and have a real cocktail. When we first arrived, we were the only ones in the bar area so were able to chat up the bartender. These ice cubes begin life as a 50# block of really clear ice. They first cut them with a chainsaw and then carve them down to about 2-1/1" square and shave off the edges. He said that it takes three hours for one to completely melt. I think this is brilliant. If I'm paying $12 for a drink I want it to taste pretty much the same all the way through the drinking process. And HE wants his craft to remain the same.
